Question

a) 42 - 36 + [ 3 of {2 % (16 +3+ 1) - 6}]​

Answer 1

Answer:

$42 - 36 + (3 \: \: of(2\% \: (16 + 3 + 1)6)) \\ = 42 - 36 + (3 \times ( \frac{2}{100} \times (20)6)) \\ = 6 + (3 \times ( \frac{2}{100} \times (20 \times 6))) \\ = 6 + (3 \times ( \frac{2}{_{5 \: \: } \cancel{100}} \times \cancel{120}_{ \: \: 6})) \\ = 6 + (3 \times \frac{12}{5} ) \\ = 6 + \frac{36}{5} \\ = \frac{30 + 36}{5} \\ = \frac{66}{5} \\ \boxed{= \underline{ \underline{ 13 \frac{1}{5} }}}$
